Description

Method and device used in user and base station of wireless communication
The present application is a divisional application of the following original applications:
application date of the original application: 2017.03.17
- -application number of the original application: 201710161931.3
The invention of the original application is named: method and device used in user and base station of wireless communication
Technical Field
The present application relates to a method and an apparatus for transmitting a radio signal in a wireless communication system, and more particularly, to a transmission scheme and an apparatus for a radio signal in a wireless communication system supporting uplink control information transmission.
Background
In a conventional LTE (Long Term Evolution) system, when a UE (User Equipment) needs to send uplink control information and uplink data on a sub-frame at the same time, the uplink control information and the data may be sent together on an uplink physical layer data channel. The number of res (resource elements) occupied by the uplink control information on the uplink physical layer data channel is associated with the mcs (modulation and Coding scheme) used when the uplink data is first transmitted. Because the MCS of the uplink data reflects the channel quality of the uplink channel, the method ensures the transmission reliability of the uplink control information on the uplink physical layer data channel.
Disclosure of Invention
Compared with the conventional LTE system, the 5G system may support more diverse application scenarios, such as eMBB (enhanced Mobile BroadBand), URLLC (Ultra-Reliable and Low Latency Communications), and mtc (massive Machine-Type Communications). Different application scenarios have different requirements on the transmission reliability of the physical layer, which in some cases may be up to several orders of magnitude different. The inventor finds out through research that if the technology in the existing LTE system is used, the uplink control information has different transmission reliabilities when being multiplexed with uplink data in different application scenarios, which may cause waste of uplink radio resources in some cases.
The inventor also finds that, in a system using multi-antenna beamforming, if different beamforming vectors are used for the first transmission and the retransmission, the uplink channel quality corresponding to the first transmission and the retransmission may be greatly different. According to the technology in the existing LTE system, the number of REs occupied by uplink control information is always related to the MCS that is transmitted for the first time. When the uplink control information and the retransmitted uplink data are multiplexed and the retransmission employs a different beamforming vector from that of the first transmission, it will be difficult to ensure the transmission quality of the uplink control information.
The present application discloses a solution to the above-mentioned problems. It should be noted that, without conflict, the embodiments and features in the embodiments in the UE of the present application may be applied to the base station, and vice versa.

The M first-class values are used to determine the number of REs occupied by the M first-class sub-signals in the time-frequency domain, respectively. The M first class values correspond to M reference values one-to-one, respectively, and the first signaling is used to determine a ratio between the first class value and the corresponding reference value. And M is a positive integer.
As an embodiment, the above method has a benefit that the serving cell of the UE maintains that the base station can dynamically adjust the number of REs occupied by the M first-type sub-signals in the time-frequency domain through the first signaling, so as to flexibly control the transmission reliability of the M first-type bit blocks.
